|a Lysophosphatidic acid acyltransferase1 (LPAT1) catalyzes the second step of de novo glycerolipid biosynthesis in chloroplasts. However, the embryonic-lethal phenotype of the knockout mutant suggested an unknown role for LPAT1 in non-photosynthetic reproductive organs. Reciprocal genetic crossing of the lpat1-1 heterozygous line suggested a female gametophytic defect of the lpat1-1 knockout mutant. By suppressing LPAT1 specifically during seed development, we showed that LPAT1 suppression affected silique growth and seed production. Glycerolipid analysis of the LPAT1 knockdown lines revealed a pronounced decrease of phosphatidylcholine (PC) content in mature siliques along with an altered polyunsaturation level of the polar glycerolipids. In seeds, the acyl composition of triacylglycerol (TAG) was altered albeit not the content. These results indicate that plastidic LPAT1 plays an important role in reproductive growth and extraplastidic glycerolipid metabolism involving PC and TAG
